ARCA

Arca Academy of Architecture

One set of rules for every medium: the mark, the palette, the typeface and the signature devices. A layout built from this page reads as ARCA.

Withdrawn values

These shades appeared in layouts as accidental duplicates. Replace them with the canonical value whenever the block is edited.

  • #FF1F8E#EE2578
  • #E93B81#EE2578
  • #DFFF3B#D8F24C
  • #D3F23D#D8F24C
  • #2563EB#070FAB
  • #0057FF#070FAB
  • #000EB0#070FAB
  • #00B4D8#0891B2
  • #2D6487#2B6585

Rules

  • One lead accent per screen; the rest work in points: a numeral, a shape, a marker.

  • Lime lives on dark only: 13.86 contrast on graphite against 1.26 on white.

  • White text on fuchsia starts at 18px Bold: 4.06 only covers large type.

  • Ultramarine is a background and text colour on light (12.61). On graphite it is unreadable (1.38).

  • Cyan as text works on dark only (4.73); on white it is a fill colour.

Never

  • Introduce new shades for a single layout instead of the canonical ones.

  • Stack accent on accent: lime on fuchsia, cyan on ultramarine.

  • Set text in steel on a dark background — 2.74 contrast.

  • Use the utility red anywhere outside forms.

03

Type

Kreadon is the only typeface of the brand. System faces are allowed as a fallback when the files cannot load.

Kreadon

A local family of seven weights, from ExtraLight 200 to ExtraBold 800. Loaded from the @meetorra/fonts package through the --assets-font-kreadon variable.

Type scale

  • 55/159 px · 500 · leading 1.0

    Display

    The first screen. One line across the container, never repeated in the layout.

  • 24/64 px · 500 · leading 1.0 · uppercase

    Section heading

    Opens every block. Always uppercase, one or two lines.

  • 18/32 px · 400 · leading 1.2

    Subtitle

    A single sentence under the section heading that explains it.

  • 48/96 px · 700 · leading 1.0

    Large numeral

    Item numbers and statistics. Colour cycles through the accents.

  • 16/24 px · 700 · leading 1.2 · uppercase

    Card heading

    Headings inside cards and lists, uppercase.

  • 14/16 px · 400 · leading 1.4

    Body text

    Paragraphs and descriptions. Measure no wider than 530px.

  • 14/14 px · 500 · leading 1.4

    Caption

    Utility labels, tags and table values.

Rules

  • Three working weights: Regular 400, Medium 500 and Bold 700.

  • ExtraBold 800 is reserved for the mark and large numerals.

  • Uppercase belongs to section and card headings, never to paragraphs.

  • Large sizes take 1.0 leading, body text takes 1.4.

  • Leave tracking alone: the face is drawn for the default value.

Never

  • Mix Kreadon with another typeface in one layout.

  • Use ExtraLight, Light or Demi — they break the rhythm.

  • Stretch the face or fake a weight with an outline.

04

Signature shapes

Four geometric forms are the second identifier of the brand after colour. Each one keeps a fixed colour.

Star

#EE2578

Accent of the first screen and of badges. The only shape that carries text on top.

Triangle

#D8F24C

Direction and movement. A large background patch on light sections.

Rhombus

#2B6585

Third plane: small elements near the section edge.

Cloud

#070FAB

A calm backdrop under photography and cards.

Rotation

Four positions are allowed: minus 15°, 0°, 15° and 90°. Arbitrary angles break the form.

  • -15°
  • 0°
  • 15°
  • 90°

Rules

  • A shape is a decorative layer: it sits under the content and never catches the cursor.

  • No more than two shapes in the decorative layer of a section. Shape icons inside the content do not count.

  • The colour of a shape is fixed and does not change between sections.

  • A shape may be cropped by the edge of the screen — that is the intended device.

  • Sizes run from 24px as a marker to 600px as a background patch.

Never

  • Outline a shape, fill it with a gradient or add a shadow.

  • Place a shape over text, over a face in a photograph, or over the mark.

  • Rotate to an arbitrary angle or mirror the form.

  • Draw new shapes in this style.

05

Devices

The recognisable details that make a layout read as ARCA even without the logo.

Apply nowSee the programme

Pill buttons

Pill radius, Bold 16px, 32 by 12 padding. Fuchsia carries the primary action, lime the secondary one.

The academy teaches design inside real studio practice.

Lime highlight

A short phrase in a lime pill inside a paragraph. Once per section.

25places in the first intake

Numeral card

Card background, 20px radius, ExtraBold numeral, Medium 14px caption.

Composition

Marker: dot and line

A 12px colour dot and a 1px white line under the item heading.

Background rhythm

White sections alternate with dark ones: one or two light sections between two graphite ones. Ultramarine appears once per page, on the application block. Grey is never a section background — it belongs to cards.

  • Card
  • Block
  • Pill

Radii

Four values for the whole site; nothing else is used.

City photo layer

Saint Petersburg blocks in the lower right of the first screen: the photograph runs under the content and is cropped by the edge.

  • Mix different radii inside one block.

  • Place two light or two dark sections in a row.
